i think the # of people realistically using <=2.4 nowadays is beyond carrying 
about, especially wrt downloading & building recent software.  mainstream 
projects (like glibc) have been requiring linux-2.6 for years now.

so if dropping this code provides a nice clean up, and you're merely requiring 
linux-2.6, then i say go for it.
